Search for neutrino charged current coherent pion production at SciBooNE

TL;DR

This study searched for neutrino-induced coherent pion production at SciBooNE but found no evidence, setting upper limits on the process's cross section ratio at energies around 1 and 2 GeV.

Contribution

First search for charged current coherent pion production at SciBooNE with no observed signal, establishing upper limits on the cross section ratio at specific energies.

Findings

No evidence for coherent pion production was observed.

Upper limits on the cross section ratio were set at 0.67×10^{-2} and 1.36×10^{-2} for 1.1 and 2.2 GeV neutrino energies.

Kinematic distributions of the data are presented.

Abstract

SciBooNE is a neutrino experiment measuring the neutrino cross sections on carbon in the one GeV region. We have performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, \nu_\mu 12^C \to \mu 12^C \pi^+. No evidence for coherent pion production is observed. We set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section at 0.67\times 10^{-2} at mean neutrino energy 1.1 GeV and 1.36 \times 10^{-2} at mean neutrino energy 2.2 GeV. The kinematic distributions of the final data sample are also presented.
